Earlier this month, our friends at The Government Attic caused quite a stir in the FOIA community with a release of over 100 vintage security posters from the National Security Agency. As it turns out, MuckRock founder Michael Morisy had a similar request with a slightly larger timeframe, and the two appear to have been consolidated.

Each poster is available for high-resolution download on the request page. Though they range from wholesome ’50s Americana …

to the significantly less wholesome Cold War imagery of the late ’50s, early ’60s …

to the straight-up you will die …

and everyone-you-know-will-die sentiment of the late ’60s …

we thought we’d focus on the more mellow phase that the NSA seemed to get into by the ’70s.

So without further ado, here’s some laid-back opsec.
